LEON P.- LOWE, OF SAN FRANCISCO, GALIIY )ItN 1A1 'APPARATUS FDR MANUFACTURING AND DELIVERING GAS- Specification of Letters Patent.

Patented April 10', 1906.

Application filed August 8,1905- Serial No. 273,311.

To all whom it may concern:

Be it known that I, LEON P. LOWE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and at-o of California, have invented oer .tam new and useful Improvements in Apparatus for Manufacturing and Delivering Producer-Gas, of which the following is a specification.

This invention relates to an improved apparatus for manufacturing and delivering p. oducer-gas, the object of the invention being to provide an apparatus by means of which part of the gas may be utilized to de liver the gas for consumption at a distance and also to eifect the production of succeeding quantities of gas and which will also onable the producer-gas to be manufactured at the same rate as it is consumed, whereby the necessity of gasholders for storing the gas is avoided. 1

In the accompanying drawings, Figure 1 is a broken side elevation of the apparatus. Fig. 2 is a plan view thereof.

Referring to the drawings, 1 indicates a gas-making chamber for manufacturing producer-gas in the well-known manner, fuel being supplied from time to time by a hopper 2 and air being supplied through the inlet The gas thus produced passes by an outlet pipe 4 into a vertical pipe 5, which may be opened at the top to permit the products of combu stion,.when preliminarily firing the fuel in the chamber 1, to pass off up the stack 6. In making gas, however, said pipe 5 is closed at the top by a valve 7, so thatthe gas passes into a washer 8, thence to a scrubber 9, and thence to a purifier 10. i From said purifier the gas passes by a pipe 11, which has two branches, one branch 12 leading to an engine 13, and Illk other branch 14 leading to a compressor 15, which delivers the gas to a service-pipe It). The compressor 15 is operated by a pitman 20, connected with the crankshaft lJ, with which is also connected the pitman 21, connected with the piston-rod of the engine 13. Thus the compressor is operated direct from the engine, driven. by part ol the producer-gas diverted from the main current which is supplied to the consumer.

' The engine 13 may be either a gas-engine or 1t may be any other engine which can be driven indirectly by means of the producergasas, for instance, a steam-cngine'oper ated by means of steam generatedby the combustion of gas. However, the gas-engine is preferable and is here shown.

From the service-pipe 16 leads a pressurepipe 22 to a regulator 23, which controls the valve 24, sup lying gas to the engine 13. By this means t 0 power generated by the engine'may be made to correspond with the pressure in the service-pipethat is to say, when the consumption of producer-gas at a distant point increases the valve 24 is automatically opened wider to supply a larger quantity of gas to the gas-engine, generating more power to operate the compressor to force the producer-gas through the servicepipe and to draw it from the gas making apparatus, and, conversely, when the consumption diminishes the valve 24 is automatically moved. to reduce the amount of gas supplied to the gas engine: By this means the amount of gas produced is made to correspond precisely with the consui'nption, so that no gas-holders are required for storing the gas, the gas being consumed as soon as it is generated. In this way the gas can be supplied at very small cost, the expense of the ap paratus being comparatively small.

I claim- 1. In combination with an apparatus for manufacturing gas, a servicepipe, a comressor for supplying gas thereto, an engine for operating said compressor, a pipe leading from the gas-makingapparatus to the coinpressor, a branch pipe leading from the latter pipe and supplying gas to operate said en'- gine, a valve controlling the passage of gas in the, branch pipe, a regulator for said valve and a pipe connecting said regulator with the service-pipe, whereby the engine is operated in correspondence with the pressure in said service-pipe, substantially as described.

2. In combination with an apparatus for manufacturing gas, a servicep1pe,a coinpressor for delivering the gas thereto, a pipe leading from said apparatus to said coinpressor, an engine for operating said compressor, a valve for controlling the motive fluid to said engine, a regulator for said. valve, and a pipe connecti ng said regulator with the service-pipe, whereby the engine may be operated m. correspondence with the pressure in said servicepipe, substantially as described.

3. in combination with. an apparatus for manufacturing gas, a service-pipe, a compressor for delivering the gas thereto ,"a pipe leading from said apparatus to said c0111- pressor, an engine for operating said c'omhand in the pressor, a valve for regulating said engine, a messes. regulator for said Valve, and a pipeeonnect- 5 ing said' regulator With the service pipe, whereby the en ine maybe operated in e0rrespondence with the pressure in said servicepipe, substantially as described.

In Witness whereof I have hereunto set my presence of two subscribing witn;

L. P. LOWE.
